Specification of Letters Patent.

Application filed January 13, 1913. Serial No. {41,615.

To all whom it may concern:

Beit'known that I, lViLmnn F. Ricimuns, a citizen of the United States, residing at Depew, in the county of Erie and State of New York, have invented a new and useful Improvement in Railway-Car Trucks, of

. which the following is a specification.

This'in'vention relates to car truck side frames, and more particularly to metal side frames of that kind, now well known, which are provided attheir opposite ends with integral depending jaws'or parts which strad-' dle'and hold the journal'boxes in place in such a manner that the journal boxes, as gether. with the car wheels and axles, can be readily removed from the truck by raising or jacking up the side frames.

Both the truck frames and the journal boxes are ordinarily made of cast metal, 'and "it is necessary forv the manufacturer,, in

' order tomeet competition, to so construct the parts that no machining will be required, *Since castings, even if made from the sametions in size and the roughness of'the surfaces of the parts. This results in an objectionable looseness, of theparts, allowing them to move relatively.- to each other with consequent wear.

The -objects of the invention are to make this type in such form that they'will fit properly without objectionable looseness or play between the partsjalso to provide simple and inexpensive retaining means for preventing the accidental dropping of the journal box from between the frame jaws.

In the accompanying drawings: Figure 46 1 is .a side elevation, partly in section on line 1-1 Fig. 2, of a car truck embodying the .inv tion. Fi 2 isj'an enlar cd fra meng g :1,

far ,I plan view therof, partly in section on lin. 22, Fig. 1. Fig. 3 is a vertical s'ectidnal elevation on line 33, Fig. 1.

ike; reference characters refer to like parts in the several figures.-

A represents the metal side frame of a car truck which is provided at each end with integral dependir portions a a forming rigid jaws which straddle and hold'the journal B. Except asherein'after mentioned, the side frame and ournel box may be of any suitable construction, the side frame preferably consisting of a single steel cast- 111g of the form shown in the drawings. The

depending jaws a a-' of the side frame'preferably do not extend downwardly to the full depth .of the journal box, so that the side frame, need not be raised or jacked up so high as would otherwise be necessary to disengage the jaws from the journal box, thus greatly facilitating the'removal of the jour-f.

nal boxes, axles, and wheels from-the car truck. Inorder to hold the journal boxes from -movement laterally or sidewise relastruc'tion .shown in the drawings, are provided at the portions thereof next to the embrace proj ting ribs C formed on "the fit betweerf the projectmg ribs C of the ournal boxand.

the jaws of the side frame,:to prevelit'movementof the journal box lengthwise-of the tive to the side frame, the jaws, in the'conside frame, the outer faces D of the ribs C and the opposing faces D of the jaws which contact therewith are made to incline orjconverge upwardly, slightly. The clearance usually required between the engaging faces of the side frame'jaws and thejournalboxes y can thus .be considerably reduced, because the slight variations or inequalities in the mterfitting parts which would prevent a v journal box from. entering between 'aws car truck side frames and journal boxes of 'ha-vmg parallel. perpendicular inner aces with the pressure on the faces due to the inclination of the sides, will wear the contacting surfaces smooth and thus allow the j ournal boxes to enter fully into the space between the jaws so that the side. frame will rest and bear firmly on the tops of the jourtent the wear on the contacting surfaces, andthe journal boxes will be held firmly in place/ The inclination of the contacting faces D D of the journal boxes and jaws is very slight. not SllfllCleIlt to cause any appreciable tendency for the side frame to creep upwardly on the journal boxes.

Means are preferably employed for preventin the accidental droppingout of the journa boxes from betweenjthe jaws of the side frames. In the construct on shown for this purpose, tapered retaining pins or keys E are provided, which extend through registering slots in the side frame and in the projecting rib C 'of the journal boxes. The

ins are preferably prevented from acci- I ental dis lacement, for instance by slitting and sprea ing or swaging the small ends of the retaining :pins or keys? Any other device may be employed for holding the journal boxes on the side frame. o

It willbeunderstood that side frames and journal boxes provided with the A inclined engaging faces canbe nsed without the, de-

scribed -holding means or with holding means other than those described.

Iiclaim as my'invent-ionz' 4 1., The combination 6f a car truck sid frame having de ending jaws, and a journalbox straddled ysai jaws, cooperating parts onsaid jaws and SflldjOlllDfil box for holding the journal box from lateral movement relatively: to said side fra1ne,'the e gaging-faces of said jaws and journal box converging upwardly, substantially as Set forth. x I

2. The combination of a'car truck side frame having jaws,'and a journal box straddled by said jaws, said journal box having projecting vertical ribs at opposite sides -which are adapted to enter into channelsin said I jaws for holding the journal box against lateral movement relatively to the side frame, the outer faces of said ribs and the opposing faces of the channeled p.

tions of said jaws converging upwardly, substantially as set forth.

The combination of a car truck side frame having a pair of integrally depending jaws at each end thereof, the opposing faces of each of said pairs of jaws converging upwardly and having vertical flanges at their opposite sides, and journal boxes, each of which is straddled by a pair of said jaws,

said journal boxes having projecting ribs, the outer faces of which converge upwardly and which are adapted to enter between theflanges of'said jaws, substantially as set forth.

t. The combination of'a car truck side frame havingjaws, anda journal box adapted to 'enter between said jaws, the inner faces of said jaws engaging the sides of the.

journal box to hold the same from move nientrelatively to the side frame lengthwise thereof,;said journal box having projecting v vertical ribs at opposite sides which are adapted to enter into channels in said jaws for holding the journal box against lateral I movement relatively to-the side frame, and holding means extending through said jaws and said ribs for preventing the removal of said box from said jaws, substantially as set forth.

5. The combination ofe car truck side frame having jaws, and a journal box adapt-. ed to enter between said jaws and to be held thereby against movement relatively to the sideframe lengthwise thereof said journal box having projecting vertical ribs at opposite sides which are adapted to engage with box from lateral movement relatively to said flanges on the jaws for holding the journal side frame, and pins extending through said ribs and said flanges for preventing theremoval of said box from said jaws, substantiall as set forth,
